iner positions, a weight 55 being provided to insure the promptperformance of this movement.

As heretofore stated, that portion of the platform which is over thatportion of the pit or chamber in which the car is placed to be loadedwhere said car emerges, is hinged, and capable of being raised. This isso that the loaded car may emerge without having the heaped-up portionof its load scraped as as it begins its ascent. After the car has beenloaded, this platform portion is raised, by hand or otherwise, and willbe held to its raised position by means of the prop or support 2i, as isbest shown in Fig, a, so that the car and its load may freely pass. inorder that it may be caused to drop down, ready for use, promptly whenthe car returns for another load, I have provided a means by which thecar will auto-- matically throw the prop back as said car reaches itsloading position. This means consists of an arm (51 secured to the sideof the car in such position that it will come in contact with said prop,and move it back, as will be readily understood. In order that said armmaynot. operate when the car is moving in the other direction, and thusbe likely to do damage, 1 have mounted it on a pivot at 62, upon whichit will swing when it comes in contact with any obstruction. It is heldnormally to its extended position by a spring 63.

In order to stop the car at the proper point, I have provided within thepit or m'aer into which the car enters a fricc tion i retarding devicein the nature of a brake. This consists of a bar 71 pivotally connectedat one-end, as by pivot 72, to the wall of the pit or chamber, andhaving a spring or other suitable downwardly-forcing device, as 73, bymeans of which it is forced downwardly with such pressure as may bedesired. As the car enters the pit or chamher and approaches its finalposition, the wheels of said car will come in contact with the bar 71,and be thereby retarded, and the car (the pressing force beingpredeterminedly arranged) will stop the car at the proper point.

Having thus fully described my said in- .vention, what I claim as new,and desire to secure by Letters Patent, is

1-. The combination, in an elevating and loading mechanism, of asuitable pit orchamber having an opening in its upper wall, a trackleading therefrom to a suitable elevation, a car adapted to travel onsaid track from said pit or chamber to the extremity of said elevation,the upper portion of the track being pivotally mounted at a point midwayof the car when the latter is in dumping position and provided withsuitable retaining devices for the car. and means for tipping said uppertrack-section and the car whereby the contents of said car may bedischarged, substantiallv as set. forth. if

.2; The combination, in an elevating and loading mechanism, of a pit orchamber adapted to contain a car and provided with an opening in itsupper wall. through which the car may be loaded, a track leading fromsaid pit to a suitable elevation, 21 car adapted to travel on said trackfrom said pit or chamber, said pit or chamber being also provided with aportion capable of being raised arranged over thatvside of the pitorchamber from which the car emerges, a sup port for holding saidvraisable portion in its upon one side of the car whereby said supportwill be pushed from its upright position as the car enters the pit orchamber and the said raisable platform portion thus permitted to descendto place.

3. The combination, in an elevating and loading mechanism, of aninclined track having a pivoted upper section onto which the carrier carmay run, a pivotsnpporl for said upper section arranged centrallythereof, guard rails secured to said upper track section beneath whichthe wheels of the car will pass whereby said car will be held securelyin position thereon, means whereby said track section with the carthereon may car thereby be discharged of its load, and means forreturning said car and track section to initial position, substantiallyas set forth. M I

:l. The combination, in an elevating and loading mecl1anism .ot anincl'incd track embodying a tilting portion centrally pivoted, a guardrail secured to said tilting portion. power devices attached to the rearend of the car for propelling said car and tilting the same togetherwith the tilting portion of the track, and means con'iprising said powerdevices and a weight suspended. directly to the rear end of the tiltingtrack portion for returning the tilting portion of track and car toinitial position when the load is discharged, the whole being arrangedand operated substantially as shown and described.

In witness whereof, I, have hereunto set my hand and seal at Harmattan,Alberta, Canada, this fourteenth day of August, A. D. one thousand ninehundred and eight.
